a) How much power is dissipated in Tom, on average? b) Now Tom jumps in the air as a result of the shock. This makes him equivalent to a parallel-plate capacitor with an area of 40.0 cm2 (the total area of his paws) and a spac- ing of 6.0 cm. What is his capacitance? c) This capacitance can be thought of as in series with the total resistance you deter- mined in part a). Now how much current (rms) goes through Tom,
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
Jerry sticks Tom’s tail in an electrical socket (Vrms = 115 V at 60 Hz). Ini-
tially, we can think of Tom’s tail as a single 22 kΩ resistor connected to the floor by his
legs. His hind legs are 65 kΩ resistors and his front legs are 55 kΩ resistors. (His body
has no resistance, and the floor is connected to a ground wire in the socket, which com-
pletes the circuit with no additional resistance.)
a) How much power is dissipated in Tom, on average?
b) Now Tom jumps in the air as a result of the shock. This makes him equivalent to a
parallel-plate capacitor with an area of 40.0 cm2 (the total area of his paws) and a spac-
ing of 6.0 cm. What is his capacitance?
c) This capacitance can be thought of as in series with the total resistance you deter-
mined in part a). Now how much current (rms) goes through Tom, and what is the
phase shift of this current with respect to the emf?
d) Tom is already planning to use a solenoid in self-defense as in Episode 3. What
should its inductance be so that the combination of the solenoid with his capacitance
gives a resonant frequency of 60.0 Hz? Ignore the resistance of the circuit.
